# This module is used by the Makefile generator to determin the following variables:
# CMAKE_SYSTEM_NAME - on unix this is uname -s, for windows it is Windows
# CMAKE_SYSTEM_VERSION - on unix this is uname -r, for windows it is empty
# CMAKE_SYSTEM - ${CMAKE_SYSTEM}-${CMAKE_SYSTEM_VERSION}, for windows: ${CMAKE_SYSTEM}
#
# Expected uname -s output:
#
# AIX AIX
# BSD/OS BSD/OS
# FreeBSD FreeBSD
# HP-UX HP-UX
# IRIX IRIX
# Linux Linux
# NetBSD NetBSD
# OpenBSD OpenBSD
# OFS/1 (Digital Unix) OSF1
# SCO OpenServer 5 SCO_SV
# SCO UnixWare 7 UnixWare
# SCO UnixWare (pre release 7) UNIX_SV
# SCO XENIX Xenix
# Solaris SunOS
# SunOS SunOS
